The Deeplore is a lengthy and dense text of the secrets of divinity, Cosmology, and aberrant states of biology, which deal with foundational knowledge the lowest portion of the Deeps, known as the Dark. It is a large volume, some 300 pages when written on velum. These copies are dear and expensive to produce according to the dwarves, as well as being considered secret knowledge and jealously guarded, therefore found exceptionally rarely outside of the dwarven holds. Duplicating these documents and providing them to non-dwarves is absolutely forbidden, punishable by Bare-Faced Exile.
Indeed, even throughout dwarvendom the volume is rare, and the exceptions to the rule that most copies can be found in Khaz Duersterkrak can likely be counted on one hand.
